For those who doubt the danger of a power supply... Even as a kid, I had the sense to not plug things in before testing sketch stuff. It was a REALLY old power supply, where you had to plug the leads into the power supply... but the sticker was gone so I didn't know which side to have the different pairs. So, I plugged it into the wall and used a stick to flip the power switch, and it promptly exploded. Fortunately, it was not a big enough explosion to break the steel casing but it definitely set off the smoke detector.

[@wachocs16]

I see linus has a lot of fear against live wires, even more at 220v. I used to use a soldering iron with a lot of spots in the cable burned from the soldering itself. One time I got shocker in the leg while simultaneously touching with my hand a metal cage connected to earth. I received a shock (220v), moved a bit scared out of surprice and continued soldering. Nothing too bad. The problem is when you grab the cable with out hand while earth connected, but touching it with a finger it wont kill you

haha, that was just a blown cap. it's fun when you just connect them directly to 230v and watch em blow, or use a small torch on the side of them (they are supposed to blow at the top) and shoot the hot blown insides at people XD they stink tho (like toxic gasses should) so do it outside

[@mattbennion779]

To clarify this was a catastrophic failure. I couldn't even pick up the box for some time because it was so hot. It was a lot more than a blown cap. This was a supply that hadn't been plugged in for a decade that had power flowing the wrong way through it, probably shorting as it flipped the breaker as well.

[@fvckyoutubescensorshipandt2718]

@@HappyBeezerStudios eh 15A can be overdriven an amp or 2 and never trip due to breaker manufacturing tolerances if you really push it and bin the breakers (usually 10% tolerances for cheap ones). The wiring can actually carry 2-3x rated current fine (ie insulation just getting warm, not melting) if the run is short. Most ampacity tables are for keeping voltage drop under 3% at stated amps rather than for temperature rise. Apparently the PSU won't mind if the voltage drops to as low as 180 (25% drop), but the breaker and wiring would with the amperage required to do that. It would be very difficult to run 3450W at 100% load anyway if using it for it's intended purpose (presumably a mining rack, and most mobos for those only have 8 gpu slots with each underlcocked = maybe 3kW).

Here in the UK the standard wall outlet is 230v 13A. If you're lucky you get ~240v which means you'd get 3120 watts maximum. Not to mention those IEC C13/C15 connectors are only rated to 10A which means your maximum power is 2400W max then you're going to melt that cable. So you'd have to get a special circuit put in from your fuse box to supply your PC. Mind you, you could probably just disconnect your water heater and use the PC to heat your domestic radiators and keep the house nice and toasty on those cold days......

[@derfurz8618]

A single Type F plug is 16A, here in Germany circuits are either 16 or 20A, so at the rated 230V you would get 3680W. So even if I wouldn’t trust anything with this depending on where you are you can theoretically use something like this safely on a standard circuit.

I love how Linus points out the input voltage rating, but totally ignores the input current limit of 10 amps right next to it. I was hoping to see some kind of generator like tony starks ark reactor inside, as that 10 A input limit gives a max output of 2400w at perfect efficiency on 240, so at a minimum it needs to pull 1050W out of thin air to attain rated capacity. If you were the low end of the input rating, it would need to probably draw near on double the rated input, if not more.

Chinese translation is bad and I am pretty sure it was saying 10Amps X2 or per unit but you gotta understand one thing.

XD They work fine at the full 16 A of a breaker circuit giving a plentiful 3600 watt. The actual limiting factor is the cabling, which often is too thin to carry such amounts of current without melting its insulation.

In our homes, not workshops or something. It's weird they don't get talked about ever. It's for heaters and AC and such, most older washers also ran on one of these.

Kind of weird to have a ground point in the middle of the transformer to get "2x 120V" from your 240V supply line and then use double breakers if you need the full 240V. Here in Germany basically all (stationary) devices that use 3phase innately are wired up directly without a plug (like literal wires into the deevice) but we also have 3 phase plugs/sockets for construction equipment etc. which can push 11kW or 22kW respectively.

Unless you know what you're doing, there isn't a safe way to really 'discharge' them (there is if you do know, though). There are however safe ways to clean them. My recommendation: buy a compressed air can or use an air compressor, and blow it through the gratings outside. Try not to backdrive the fans *too* hard.

Take it from a physiology grad and electronics nerd of 40 years, even a mains capacitor in a small PSU would 100% be able to yeet you across a room (and potentially kill). A battery powered TENS machine is enough to make people punch themselves in the face or fall on the floor.. It's your muscles which do the real work, the electricity just has to be enough to trigger the nerves. Depending which particular muscles contract, it'd be able to throw you further than you could willingly jump, so depending how jacked you are, across the room is 100% possible. SMPS bus caps are DC, so they'd usually cause one violent muscle contraction rather than the paralysis seen with AC electrocution. The bus voltage on a 230V powered PSU is 325VDC, enough to push 800mA through a person (Assuming the 400 ohm human model used in TASER testing). 10mA is enough to cause strong muscle contractions, 30mA can stop a heart.

[@pottedrosepetal6906]

I mean I can try to guess what he meant if you want. He is talking about electromagnetic interference (emi) which occurs when random stuff hits a circuit, like radio waves or some other load switches on or off in the circuit. Basically just noise of some sort. Now, firstly about what capacitators do. They delay power transmission slightly, so high short peaks get swallowed by it and then slowly drained. Then they also make it so only AC gets through (thats the main use for capacitators in most electronics - just letting AC through and isolating a network from the DC current). This probably helps in terms of offsets or DC noise. But I am guessing that its actually another cap that prevents this than the one talked about here. Lastly capacitators act as a short when the frequency is very high, as in a few megahertz or gigahertz. Basically a capacitator has one important property: resistance goes up when frequency is low, and down when its high. Now, grid frequency is only 60Hz which is basically nothing. However, noise frequency is arbitrarily high, most of the time a few hundred or thousand times the grid frequency. So that part gets transmitted to ground, however 60Hz does not since it gets blocked or sees a high resistance. (note what I said above about swallowing short peaks - thats basically the same as what I said just now, just another way to look at it). why is EMI bad? Well, just imagine it as additional power that goes into the circuit. That power ends up somewhere. Since there are other caps, they might just go right through there, resulting in some isolation that is supposed to be fine to, well, not be fine and this could lead to bad stuff such as power peaks fucking up stuff or some arcing or whatever. Its just uncontrolled, and you dont want that when there is lots of power draw.
